摘　　要：通过对山坡道路建设产生的意义,不同区域道路侵蚀类型,道路侵蚀的影响因素进行了分析研究,在充分考虑植物抗旱性的基础上,通过对道路适生植物资源及植物抗旱性初步研究,提出道路防治体系设计与植物路植物措施配置原则、技术体系、并提出适应路面、路坡栽种的草灌种类并对植物路水土保持减沙效益进行了评价研究。A study was conducted on the Loess Plateau to find ways to control erosion. After evaluating the soil loss caused by road building in different regions ,the affecting factor of the road erosion type and difference in topographical succession are analyzed. With the consideration of drought-resistance of vegetation species and sources of species suitable for growing on roads ,the criteria for designing controlling system and biological measures for road erosion are put forward. Shrub and grass species were also suggested for the control of road erosion, and sand-decrement result of soil and water conservasion of biological road are evaluated and studied.
